Tutorial: Create a Gear Rig Using Expressions After Effects

By Joey Korenman

Here's how to rig a gear.

In this lesson we'll be using some expressions that might look a bit complicated, but we promise that you'll get the hang of them. Joey is going to walk you through the whole process of making this gear rig turn using just a bit of math. Don't worry! It's not that bad.
Check out the resources tab for the expressions that Joey used in this lesson if you don't want to type them all in by hand, or if you want to check your work if you're typing them out as you go along.
